python tuple怎么用

tuple( seq )

>>>tuple([1,2,3,4])

(1, 2, 3, 4)

>>> tuple({1:2,3:4})    #针对字典 会返回字典的key组成的tuple

(1, 3)

>>> tuple((1,2,3,4))    #元组会返回元组自身

(1, 2, 3, 4)

#!/usr/bin/python

aList = [123, 'xyz', 'zara', 'abc'];

aTuple = tuple(aList)

print "Tuple elements : ", aTuple

Tuple elements :  (123, 'xyz', 'zara', 'abc')
